Abstract
The invention discloses a method for flotation separation of copper lead sulfide ore and belongs to the field of flotation separation of ore. The method for the flotation separation of the copper lead sulfide ore comprises the steps that sample ore is weighed and distilled water is added to the sample ore; pulp mixing is carried out by means of a hanging slot type flotation machine; a pH regulator is added into the pulp to enable the pH value of the pulp to be 4-12, and then a depressor which is 2,3-dyhydroxy propyl group disulfide generation sodium carbonate, a collecting agent which is dithiocarbamate and a foaming agent which is terpenic oil are added in sequence to carry out a flotation separation test, wherein the time interval for adding of the agents is 1-3 min and the flotation time is 3-6 min; the froth product obtained by flotation is ore concentrate, the products in a slot are tailings, and the ore concentrate and the tailings are dried and weighed to calculate the recovery rate. According to the method for the flotation separation of the copper lead sulfide ore, due to the fact that the 2,3-dyhydroxy propyl group disulfide generation sodium carbonate is adopted to serve as the depressor used for flotation separation of the copper lead sulfide ore, a good flotation separation effect can be obtained within a wide pH range, the 2,3-dyhydroxy propyl group disulfide generation sodium carbonate is a flotation reagent with obvious environmental protection benefit, the preparation cost of the flotation reagent is low, the depressor effect is good, and obvious selectivity can be achieved.
